Every year around June, the rainy season arrives in many parts of Japan. Although you may be lucky to enjoy some dry days later in summer when the rainy season ends, most people are resigned to experiencing a combination of hot and humid weather from now until the beginning of fall.

If you've ever experienced muggy meather, then you surely know how the humidity clinging to your skin can make normally comfortably warm temperatures very unpleasant.

Bottles to the rescue

Pharmacist and Twitter user ひろふみ Hirofumi (@hirokoujiKanpo) posted a way of dehumidifying your room on his Twitter account.

You don't need to buy a dehumidifier, use your air conditioner or a fan, whether electric or hand-powered.

This method not only makes your room cooler, but it's also good for people who don't like the artificial breeze generated by air conditioners.

Hirofumi introduced the idea of putting frozen bottles in a bowl and placing it in your room!

He says that this dehumidifies the room by collecting the moisture in the air as it condenses on the bottles' surface.

Also, after the contents of the frozen bottles have melted, they can be drunk as water.

If you use it in your bedroom, it's also a great way to rehydrate yourself when you wake up in the middle of the night and are feeling thirsty.

You can use any freezer-safe bottle, preferably reusable ones. It's generally recommended to leave 1/4 of a bottle empty when you freeze it to avoid damaging it when it expands.

This easy life-hack seems to have been appreciated by many online, as it elicited numerous comments, such as:

Why not give it a try this summer?
